This LICENSE.txt travels with the data files in this archive. The transfer functions were
distributed via the AusMT portal, which serves only openly licensed Australian magnetotelluric
releases; the licence above is the custodian's, set in the survey's survey.yaml. Reuse under the
terms of that licence (https://creativecommons.org/licenses/by/4.0/).

Changes were made: 146 of the 189 served files differ from their archive member in the sign of the >HEAD LAT value, restored from the same file's >=DEFINEMEAS REFLAT by _tools/repair_edi_header_hemisphere.py, and in nine record lines inserted after >INFO; no data value, frequency or other header value is changed, and each delivered file is kept unaltered under provenance/as-delivered/. The other 43 served files are the archive's members unchanged. ABR196A is withheld because the impedance sign gate refuses it, and its delivered file is kept unaltered as well.. AusMT serves derived renditions (canonical EMTF XML; MTH5 where available) generated from the deposited files; per-station conditioning notes are recorded in the machine-readable products.
